VANIIVIAL-RELEASING DEVICE.

SPECIFICATION forming part of Letters Patent No. 530,48*?, dated December 4, 1894.

Application filed April 12,1894. Serial No. 507,280. `(No model.) i

` To 1/ZZ whom it may concern: t i Be it known that I, HANS LARSEN, a citizen of the United States, residing at Newell, in the county of Buena Vista and State of Iowa, have invented a new and usetuldA nimal-Re` leasing Device, of which"fhe'"following is a specification. My inventionrelates to improvements in those stanchions which are made in series and capable of being released in unison and by a simple and quick movement, whereby the animals secured thereby will be freed simultaneously; and the principal object of theinvention is to provide a device of this class which may be released with greater ease and speed thanordinarily, and one which can be manufactured at a low cost.

Afurther object of the invention is to provide a device whereby the animals will be allowed more ease when secured thereby, and

one which will not make it hard for them to rise from a lying position.

In the accompanying drawings: Figure 1 represents a perspective view of a portion of a cow stable, showing my improvements in use; Fig. 2, an enlarged side elevation of one section of the stanchion; Fig. "3, a longitudil nal section taken through the upper beam or box of the device and showing how the chains are attached thereto; Fig. 4, a detail perspective showing the construction of the locking pin for holding the chains;

The reference numeral 1 indicates the framework of the stalls, which consists ot' vertical and parallel beams secured at their tops to the transverse beam 2, or to the top of the stable.i

3 indicates the pin or bar box, which contains the devices for supporting the upper ends of the chains, and which is secured to the vertical beams 1, by bolting or otherwise. The box 3 extends horizontally and co-operates with the foot-board 4, which extends similarly and is secured tothe lower ends of the beams 1 at a point directly adjacent to the floor. i

5 and 6 indicate the chains for securing the animals in place, and these are essentially two in number, though I have shown three sets in the drawings. The chain 5 is permanently secured to the beam or board 4, by

`justed to the ring the chain 5 is passed, thus giving it a i connection with chain 6, and allowing the ring 11 to slide freely ou the chain 5. Secured to the lower end of the chain 6 is the ring 15, which receives the chain 5, and by this means the lirst chain is `slidably connected to the latter. Thus it will be seen `that the chain 5, when the device is in oper` rative, position, is connected securely to both the box 3 and board 4, and that the chain 6 is slidably connected to the rst chain so as to form a loop thereon for the reception of the auimals neck, and that this loop is mov able vertically on the chain 5 so as to be adposition which the animal occupies.

i The chains 5 are secured to the box 3 by means of the.longitudinally-extending bar 16, which extends throughout the longitudinal extent of the box, and projects out beyond each end thereof. Located in the box 3 are the blocks 17, which till the space not occupied by the bar 16, and serve to guide and steady the same. These blocks 17 are secured in place by the bolts 18, which pass through them and the box 3, and which have their lower ends `formed with hooks 10, by which chains 6 are secured in place. Secured to the bar 16, at the left of each Vblock 17, are the eyes 18, which are two for each block and which are longitudinally aligned on the bar. In each pair of these eyes the pins 19 are arranged so as to be longitudinally movable therein, and i provided with the coiled springs 20, by which they are given a normaltendency toward their respective blocks.

21 indicates a series of eyes which are secured to the interior of the box, and onejust to the left of each block 17 and in the path of the pins 19. Through these eyes the pins 19 pass on their way to the blocks, and by these means they are steadied and rendered rigid. The coiled springs 20 bear, at their right-hand ends, against the studs 22, which project upwardly from the pins 19, and through the longitudinally-elongated slots 23, on the top of the box 3. These slots 23 are one for each stud 22 and are formed to permit movement of the studs, and consequently the bar 16.

Securedin the upper end ofthe studs 22 are the rings 24, which are adapted to serve' as a convenient means for grasping the studs and by which they may be' moved in their slots. The chains 5 enter the box 3 by way of the openings 25, formed in the rear face of the box and between the eyes 18a and 21 of each block 17, so that the links 8 will be in position to receive the pins 19, and thereby secure the chains. Secured to each end of the box 3, and on opposite sides of the project.- ing ends of the bar 16, are the eyes 26, which are two for each end of the box, and which are adapted for the reception of the pin 27. The pin 27 is adapted to pass through the eyes 26 and through the openings 28 in the ends of the bar 16, and by that means hold the bar incapable of movement. Only one pin is provided, and this may be used at either end, as convenient.

To use my invention the chains are connected to the box 3 and board 4 and to each other, as explained, and the lower end of chain 6 passed around the animals neck and secured to the chain 5 by means of the ring 15, thus securely fastening the animal and yet leaving him able to move his head up or down throughout the extent of the chain 5. It will be understood that the two chains 5 and 6, and the bar 16 with one pin 19, are the only essentialities of the invention, and that these may be multiplied ad infinitum, according to the number of animals to besecured. Thus I have shown three sets of chains, with their appurtenances, and it will be obvious that this does not exhaust the number possible.

To release all the animals at once, all that will be necessary is to withdraw the pin 27 and pull or push on the bar 16, according to the end of the box at which the operator stands. This will move the pins 19 to the left and disengage the links 8 and pins 19, thus allowing the chains 5 to drop down through the ring 11, and thereby releasing the animal secured by the chain. By this means all the animals in a stable may be simultaneously released, so as to allow their escape in case of fire, or to turn them out of the stable. If, however, it is desired to release only lone animal, this may be done by moving the stud 22 of the pin 19 which holds the animal, thus causing the pin 19 to move independently and release the link 8 engaged by it. By this construction the animals may be secured, since it would be quite inconvenient to secure them all at once.

In Fig. 1 I have shown the chains in three different positions; the chains on the extreme left being shown detached and in thepositions they will occupy when the animal has been released; the next set, with the animal attached and showing him with his head raised; and the third, with the animal attached and with his head down.

Having described my invention, what I claim is- The combination with upper and lower stanchion-bars, of a chain permanently secured at its lower end to the lower bar, a spring-actuated bolt mounted upon the upper bar and adapted to engage a ring on the upper extremity of said chain, and a second chain permanently secured at its upper end to the upper bar and provided at its lower end and at an intermediate point with rings which are slidably tltted upon the first chain, substantially as specified.

. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HANS LARSEN.
